Hi Marcus,
Right, I have resubscribed not using nabble.
I installed it originally using pacman and GNU Radio companion is enabled and
has been working more or less. It just throws up messages that certain things
are missing, that I then install from binary.

Hello,
Trying the tutorial three - python in gnu radio and the 'if_else' mod file. I
get this run-time error even with the tutorial/solutions file so it might be a
build thing.
Basically when it runs with the added if val == 1: block it raises an

Hi Kartik,
Well, no I would think there ought not be an error in the tutorial, but the
fact remains that if I run the ‘if_else_mod.py’ from the
~/solutions/gr-tutorial/examples/tutorial3/python/ folder I get the exact same
runtime errors, so it might be something in the build. I attach my own
Hi Martin,
Sorry, I did forget to put all that in, still learning including how to use a
list for help.
Right - I have it on a VM running Archlinux (4.8.13-1 - I only started a week
ago) and I used pacman to install the package gnuradio 3.7.10.1-3.
At that point after installing the gnuradio pa
Hi Sreeraj,
Ok, thanks, trying that – it tells me no apparently and is offering to upgrade
a heap of stuff – including some stuff I only just installed a couple of hours
ago (!) – and I also – to fill you in – removed my gnuradio installation and
re-did by installing gnuradio-companion package
Hi Sreeraj,
Did the upgrade.
I still get the error I’m afraid. Also with the cloned example file in the
solutions.
I can now get the subsequent programming exercises to work – well, the next
part at least because I am still trying to fix this – so I may carry on with
that and maybe some solutio

Hi Marcus,
Thanks for the detailed instructions (and don't worry I understood the SWIG
comment ;-) )
I did as you suggested and the Boost warning DID disappear - and it was only
necessary to put the new FindBoost.cmake file in the gr-tutorial/cmake/Modules
directory.
However, unfortunately th
I would further add that it still doesn't run from inside GRC because the
tutorial four changes are negated even if you do not regenerate the file.

Hi Tellrell and others,
I have been having similar problems while going through the various tutorials
and have come up with some workarounds (with help from a python expert – my 21
year old son) and am now getting to the bottom of it.
I have fixed it by adding the following lines to the -_init__

I know it's a kludge but I've been working on this steadily when I can to try
and work out why it hasn't been working despite following all directions in the
tutorials, and so far this is the only way to get it to work.
It's how I got the python and C++ blocks in the Guided Tutorial
Hi Marcus,
According to the build/install_manifest.txt it installs to:
/usr/local/lib/python2.7/site-packages/
And various other /usr/local/ paths as appropriate e.g. /usr/local/include/
/usr/local/share/
Does that make sense?
I followed the instructions - exactly - to use gr_modtool to cre
Thanks Marcus,
I can see it makes no sense that adding lines to the init.py telling it to look
in the build directories fixes the problem and it's probably not a viable long
term solution.
I will continue investigating.
However, 'it' (python, the GRC) does go to the install tree i.e., to the

Hi Marcus,
Thanks, yes, I agree totally.
In brief I have tried this and it has broken everything. From my quick search
around it seems to be a problem specific to Arch (though I guess we've
gathered that by now) to do with Arch not having (or indeed approving of
apparently) a /usr/local/ direc

I downloaded the file fm101.8MHz_1Msps.cfile (from

Hi Shane,
I believe this might be the solution. According to James Shimer on this thread,
it's a race condition in the python code - read on down the thread. Anyway, the
solution works, I tried it.
